| | * | ARM: 7116/1: debug: provide dummy default option for DEBUG_LL UART choiceWill Deacon2011-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Defaulting to DEBUG_ICEDCC will cause systems to hang during boot unless a hardware debugger is listening to the debug comms. channel. This patch adds a dummy UART option as the default DEBUG_LL choice which requires the platform to do the right thing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DEBUG_ICEDCC support is just another DEBUG_LL choice and selecting it along with other DEBUG_LL options doesn't make much sense.

| | * | ARM: 7073/1: debug: augment DEBUG_LL Kconfig help to clarify behaviourWill Deacon2011-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enabled DEBUG_LL hardcodes the UART address into the kernel and results in a non-portable kernel image. Since this option is only intended for use when debugging early boot failures, supporting multiple platforms in such a configuration is not the intended use-case. This patch documents this limitation in the DEBUG_LL Kconfig help text, so that users are aware of the portability restrictions that are associated with enabling low-level debugging support.

| | * | ARM: 7072/1: debug: use kconfig choice for selecting DEBUG_LL UARTWill Deacon2011-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enabling CONFIG_DEBUG_LL (which is required for earlyprintk) hardwires the debug UART address into the kernel, so that we can print before the platform is initialised. If the user inadvertently selects multiple platforms with DEBUG_LL enabled, the UART address may not be correct and will likely cause the kernel to hang in the very early stages of boot. This patch, based on a skeleton from Russell, uses a Kconfig choice for selecting the DEBUG_LL UART, therefore allowing the user to make a choice about the supported platform when DEBUG_LL is enabled.

| | | | * | | ARM: gpio: make trivial GPIOLIB implementation the defaultRussell King2011-08-12

This means that by default, you get the trivial implementation and only have to do something extra if you need to. This should encourage the use of the trivial default implementation. As an additional bonus, several gpio.h header files become empty.

Provide the standard gpiolib gpio_to_irq() for everyone, but allow platforms to override it if they wish. Add the neccessary overrides for those platforms which do not use the standard definition.
